I bought an ender 3 S1 Plus back in October 2023. It was a dream machine till I ran into an obstacle in beginning of March 2024. AB Temp error (-15 degrees) error. can't print anything. I changed thermistor, didn't work. I changed the entire block, didn't work. Bed heating is fine, nozzle temp does not work. Now I need to know if my purchase on Amazon.in is covered under any warranty. Or how to fix this temperature problem. My printer has been idle for about three weeks now. Somebody please help me. Any suggestion is highly appreciated. Thank you.
